This boat is intended as a lightweight pocket cruiser with easily
driven lines and a traditionally inspired sailplan. The epoxy lapstrake hull
is based on a proven US type.
The design is a deliberately lightweight and small interpretation of the
competition's aims to ensure that the boat can be rowed and trailored on
land by two people relatively easily. A small outboard (not shown) may also
An important innovation is the addition of twin daggerboards designed to
provide both upwind performance and support when the boat is grounded -
streamlined blocks are attached part way up the length of the twin
daggerboards to act as 'legs' when bottomed out. This feature is
particularly important in the UK, as our small boat cruising enthusiasts
tend to prefer to sleep on board up a creek in preference to using tents at
the water's margin. This may seem a curious habit given the tides seen in
the British Isles, but may be due to the traditional hostility of the
I envisage a T-section rudder to allow a short rudder to be used that will
not require to be withdrawn when beaching. The long skeg is intended to
provide a degree of directional stability and my general arrangement
includes a pinrail that I hope will allow the skipper of this boat to make a
cup of tea from time to time.
In my view, this boat's main drawbacks are:
- that it is a relatively complex building job
- that it is best sailed flat, and
- that the accommodation has been kept to a minimum in favour of an
easily driven hull.
The yawl that's nearly a schooner, the schooner that's nearly a yawl,
and the periauger with two similar sails have been popular small boat rigs
in many places for a very, very long time, even if they are rarely seen now.
I was recently reminded of this when I began to research a British inshore
working boat, the Humber gold-duster, and again when considering the Hampton
boat and the Kingston lobster boat as described by Howard Chappelle and John
Gardner. Each of the three types were seen sporting twin spritsails of
similar size (though not always in the latter two cases), and each were
In particular, the Duster evolved for the purposes of racing to meet ships
coming in to the Humber estuary in order to sell boatman's services, which I
feel must be some sort of recommendation. Spritsails also have a reputation
for dumping wind during gusts, which must be an important consideration when
using a lightweight boat such as this for coastal cruising.
So why not bring the twin spritsail configuration back into use?
Finally, I should say that I think anyone who built this boat and wished to
rig it very cheaply might find that using two second-hand Laser rigs will
serve, at least on a temporary basis.
In line with the confining lines of the hull and the need to keep
windage to a minimum, the enclosed sleeping area has been made as small as
possible. However, I envisage a tent slung over the boom with the purpose of
creating a sheltered cooking and living area when at anchor, or when
beached. Storage areas are available under the cockpit seating.
Safety and seaworthiness
Most boats this shoal are really just large dinghies, and this is no
exception. It cannot normally be made self-righting, despite the ballast in
its keel and the natural buoyancy of the wooden masts, and so I feel it is
important to keep the emergency buoyancy at the ends - the cabin and under
the after-deck - with the cockpit relatively open in order to give the crew
a chance of righting the boat in a capsize. (I have too many times struggled
to right a boat that floats too high out of the water on its side.) The
storage under the cockpit seating is therefore enclosed only by a
'basketwork' of slats.
Using scantlings based on 6mm ply for the hull and 5mm ply for decks,
doghouse etc, I estimate that the combined weight of the hull and gear is
490lbs. Allowing for 650lbs of crew in the cockpit, and 72.5lbs of gear in
the each of the cabin and cockpit storage areas places the centre of gravity
at just 10ft aft of the stem.
By a happy coincidence, at a displacement of 1350lbs, the centre of buoyancy
is likewise 10ft from the stem.
I therefore suggest that any additional ballast should be placed so that it
is centred at this same point. On the principle that ballast should be
distributed over a reasonable distance fore and aft, I would suggest a 220lb
iron shoe 12ft in length, 3in wide and 2in deep be attached to the keel with
its centre at ten feet from the bows. I suggest that sandbags may be used to
provide trimming ballast as needed.

scantilings indicated; in addition the masts should be of the best Oregon
